SPECIFICATION forming part of Letters Fatent No. 542,248, dated July 9,1895. Application filed July '1, 1894- Serial No. 616,789. (No model.)

To aZZ whom, it may concern.-

Be it known that I, EDWARD N. GAUDRON, of Brooklyn, inthe county ofKings and State of New York, have invented a new and Improved Funnel, ofwhich the following is" a full, clear, and exact description.

The object of the invention is to provide a new and improved funneldesigned for conveniently filling liquids into bottles, lampfounts,barrels, and other vessels without danger of overflowing.

The invention consists of an aircontrolled cut-0E valve mechanismcomprising a valve and a piston, of which the valve controls the inletof the liquid from the funnel-body to the nozzle, and the pistoncontrols the said valve to force the latter to shut.

Theinvention further consists of a piston, a valve, a liquid-chamber,and a compressed-air chamber, all arranged in such a manner that thevalve closes the liquid-chamber by the action of compressed air on thesaid piston.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying I drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is a sectional side elevation of the improvement, showing thevalve open. Fig.

2 is a similar view of the same, showing the valve closed. Fig. 3 is anend elevation of part of the improvement. Fig. 4 is a transverse sectionof the same on the line 4 4 of Fig. 2. Fig. 5 is a sectional plan viewof the nozzle on the line 5 5 of Fig. 2. Fig. 6 is a sectional sideelevation of a modified form of the improvement. Fig. 7 is a sectionalplan view of the same on the line 7 7 of Fig. 6. Fig. 8 is a sectionalside elevation of another modified form of the improvement. Fig. 9 is asectional plan view of the same on the line '9 9 of Fig. 8. Fig. 10 is asectional 'side elevation of the improvement as arranged for fillingbarrels, and Fig. 11 is a transverse section of the same on the line 1111 of Fig. 10.

The improved funnel is provided with a funnel-body A, from which extendsa nozzle B, preferably made in the shape of a pipe, having its upper endprojecting through a dished bottom 0, arranged in the funnel-body A, asis plainly shown in Figs. 1, 2, and 4. The upper end of the nozzle B isclosed, and the said nozzle is preferably provided with a transversepartition B, extending from the closed top to the lower end of thenozzle, the said partition forming a liquid-inlet chamber B and acompressed-air chamber B The upper end of the liquid-chamber B is formedwith a valve-seat B extending sidewise into the funnel-body A, directlyabove the bottom 0, and the upper end of the compressed-air chamber Bopens into a cylinder 13''", arranged in alignment with the seat E thesaid cylinder extending through one side of the funnel-body A to theouter air.

q The seat B is adapted to be closed by a valve D on one end of thepiston-stem D, which carries the piston D operating in the cylinder BThe outer end of the stem D is guided in a suitable cross B held in theouter open end of the cylinder 13, andon/the extreme outer end of thestem D is secured a knob D adapted to be taken hold of by the operator.Thelower part of the valve D is guided in a channel 0, formed in adished bottom 0, so that the liquid poured into the funnel-body Areadily drains into the said channel 0', opening into the-liquid-chamberB (See Fig. 4:.)

In the funnel-body A, above the upper closed end of the nozzle D, isarranged a strainer E, so as to prevent impurities from passing to andthrough'the nozzle D.

The operation is as follows: When the pis ton is in the position shownin Fig. 1, then the valve D is away from the seat B and the piston D isin its innermost position in the cylinder B Theliquid poured into thefunnelbody A can readily flow through the open valve-seat B into theliquid-chamber B and down the same into the vessel to be filled. Whenthe liquid rises in the vessel until it finally becomesalmost filled,then the liquid enters the lower end of the nozzle B, and consequentlypasses into the compressed air chamber B in which it rises, and therebycompresses the air contained in the said chamber B The compressed air inthe said chamber B acts on the piston D so as to finally force thelatter out, whereby the valve D is forced to its seat B", therebyclosing the upper end of the liquid-chamber B and consequentlypreventing the further flow of the liquid from the funnel-body A intothe vessel, thereby preventing overflow. The surplus liquid contained inthe funnel-body A will remain there until the funnel is moved onto anempty vessel, and the valve D is again opened by the operator pressingwith his finger the knob D inward. In doing so the piston-valve is movedback to its normal position. (Shown in Fig. 1.)

It will be seen that by the arrangement described the liquid in thevessel to be filled is used as a piston in the compressed-air chamber Bto compress the air therein and to actuate the piston for forcing thevalve D to its seat B which piston D forms, in eifect, a movable wall ordiaphragm for the compressedair chamber.

I do not limit myself to forming the liquidchamber and thecompressed-air chamber by a transverse partition in the nozzle B, asthis may be greatly varied-for instance, as shown in Fig. 6, in whichthe nozzle H is provided with an inner concentric tube I1 bent at itsupper end through one side of the nozzle to form the valve-seat H forthe valve I on the piston-stem, while the nozzle H is formed at itsupper end with the cylinder H in which operates the piston 1 connectedby the stem 1 with the valve I. hen the latter is open, as shown in Fig.6, then the liquid poured into the body A flows through the seat H intothe concentric tube II to fill the vessel until the lower end of thenozzle is closed and the liquid rises in the nozzle to compress the airand to actuate the piston l to force the valve I to its seat H.

As shown in Fig.8, the nozzle F is provided at its upper end and at oneside with the valveseat F, and the concentric tube F connects at itsupper end with the cylinder F containing the piston G connected by thestem G with the valve G, adapted to be seated on the seat F. When theliquid rises in the vessel, it finally passes into the tube F tocompress the air therein and to actuate the piston G2 to force the valveG to its seat.

As illustrated in Fig. 10, the funnel is arranged for filling barrels,and in this case the funnel-body is dispensed with and the nozzle J isprovided at its upper end with an inlettube J, connected by hose orother means with the liquid-supply. In this inlet-pipe J is arranged avalve-seat J adapted to be closed by a valve K, connected by a stem Kwith a piston K The nozzle J is provided with a partition forming theliquid-chamber J connected at its upper end with the seat J and havingits lower end J opening at one side of the nozzle J. The compressed -airchamber J extends from the lower end of the nozzle J to the cylinder Jin which operates the piston K of the piston-valve K. A stop J 6 for thevalve K is also arranged in the inlet-pipe J to limit the openingmovement of the said valve. The operation is the same as previouslydescribed in reference to the pre viously-described forms.

It will be seen that when the valve D begins to close by the action ofthe compressed air against the piston D then the suction action of thewater flowing through the nozzle 13 greatly assists in rapidly seatingthe valve on its seat. The pressure of the remaining liquid in thefunnel -body securely holds the valve D closed to permit of moving thefunnel to another bottle without danger of losing any of the liquid inthe funnel-body.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A funnel, provided with a piston and avalve, of which the valve controls the inlet of the liquid from thefunnel body to the vessel, and the piston controls the said valve toforce the latter shut, substantially as shown and described.

2. A funnel, provided with a liquid chamber, a compressed air chamber, apiston, and a valve, all arranged in such a manner that the aircompressed in the said compressed air chamber acts on the said piston toforce the valve shut on the said liquid chamber, substantially as shownand described.

A funnel, comprising a piston, a valve, and a divided funnel nozzleforming a liquid chamber and a compressed air chamber, the said liquidchamber opening at its upper end into the funnel body and being adaptedto be closed by the said valve, while the upper end of the compressedair chamber connects with the said piston to actuate the latter and toforce the said valve shut on the said upper end of the liquid chamber,substantially as shown and described.
